This is how I have it, but in addition to 3 TVs, that second leg is also
going to my 4 mythtv tuners.  My cable modem was on a leg marked 8db, while
the TVs and myth were on the one marked 3db or something like that.  Just
for kicks I reversed the two, and so far I have no artifacts on any tuner,
or TV.  I must be right at the borderline of usable signal, and I guess the
specs stamped on the splitters is a wild guess.

I'm seriously considering going all OTA soon, since the networks are pretty
much all that's available in the clear, and the OTA signal is more reliable
than comcast, despite being 40+ miles from broadcast using a coat hanger and
tin foil DIY antenna.
